Wallpaper Swapping with Hammerspoon

Hammerspoon is a pretty nifty tool. It’s kind of difficult to explain what it does, but the best I can do is that it allows you to use Lua to script actions on your Mac and, crucially, respond to events. For instance, I use Hammerspoon to lauch all my applications when I get to work and lay them out on the screen in the order that I like. I can do this because I was able to attach a location listener to work’s location, and execute Lua code on arrival. The amount of things that you can do with this tool is pretty stunning. It’s become an indespensible part of my macOS experience.
